The valve and rim manufacturers need to step up here. We know (from the innertube people) that the locknuts are important but we also all know they sit very poorly on the rime surface (like they are not so important) and scratch that pristine rim surface if tightened enough to stay on through all the vibration a rim gets.
So, get with it! Offer us some properly shaped plastic washers that will fit flush with both the complex curved surface of the rim and the lockwasher. Yes, you will have to provide quite a few variations because rims vary so much, but ... it is you who are telling us this is important. And isn't it your obligation to provide us the means to install these critical parts without damaging the finish of our $1000 wheels? (These washers probably need to have wrench flats so they can be held in proper alignment with the rim. Perhaps a small wrench could be included.)
With these washers, properly installed, we will finally be able to have wheels done right. No gaps under the edges of the lock nuts and no scarred anodizing.
